HTTPS and SSL3_GET_SERVER_CERTIFICATE:certificate verify failed, CA is OK

Question

I am using XAMPP for development. Recently I upgraded my installation of xampp from an old version to 1.7.3.

Now when I curl HTTPS enabled sites I get the following exception

Fatal error: Uncaught exception 'RequestCore_Exception' with message 'cURL resource: Resource id #55; cURL error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (60)'

Everyone suggest using some specific curl options from PHP code to fix this problem. I think this shouldn't be the way. Because I didn't have any problem with my old version of XAMPP and happened only after installing the new version.

I need help to figure out what settings change in my PHP installation, Apache etc can fix this problem.

It's a pretty common problem in Windows. You need just to set cacert.pem to curl.cainfo.

Since PHP 5.3.7 you could do:

1. download https://curl.haxx.se/ca/cacert.pem and save it somewhere.
2. update php.ini -- add curl.cainfo = "PATH_TO/cacert.pem"

Otherwise you will need to do the following for every cURL resource:

curl_setopt ($ch, CURLOPT_CAINFO, "PATH_TO/cacert.pem");
